Abstract Loneliness is a subjective and unpleasant experience associated to a variety of physical and mental health problems. Older people face an elevated risk of loneliness. It is measured through self‐reported questionnaires, among which the most widely used one is the University of California, Los Angeles (UCLA) Loneliness Scale. The latest version of this scale is called UCLA‐3, and it has not been validated in Spanish elderly population. This article aims to present a validation study of the Spanish version of the UCLA‐3 for its use with older people, by establishing its reliability and validity. Data were obtained from the second wave of a longitudinal research conducted with older adults attending Lifelong Learning programs. The sample consisted of 335 people aged 55-years old or older. Sociodemographic data were collected, and loneliness was measured with the UCLA‐3 and the de Jong Gierveld Loneliness Scale. Results have partially replicated a three factor structure already found in the literature in other populations. The present work provides relevant and innovative evidence, as this is the first time that the UCLA‐3 was analysed using ESEM statistical approach in a Spanish elderly sample.

加州大学洛杉矶分校孤独量表（第 3 版）在西班牙老年人群中的验证：探索性结构方程模型的应用

摘要 孤独是一种主观的、不愉快的体验，与各种身心健康问题相关。老年人面临更高的孤独风险。它是通过自我报告的问卷来衡量的，其中使用最广泛的是加州大学洛杉矶分校（UCLA）孤独量表。该量表的最新版本称为 UCLA-3，尚未在西班牙老年人口中得到验证。本文旨在通过确定其信度和效度，对 UCLA-3 西班牙语版本的老年人使用进行验证研究。数据来自对参加终身学习计划的老年人进行的第二波纵向研究。样本包括 335 名年龄在 55 岁或以上的人。收集了社会人口学数据，孤独感是用 UCLA-3 和 de Jong Gierveld 孤独量表来衡量的。结果部分复制了在其他人群的文献中已经发现的三因素结构。目前的工作提供了相关和创新的证据，因为这是第一次使用 ESEM 统计方法在西班牙老年人样本中分析 UCLA-3。
